LESTER D. SWART, OF AUBURN, NEW YORK.

CORN-HUSKING MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 732,468, dated June 30, 1903.

Application filed August 4,1902.

To all whom it may concern.-

Be it known that I, LESTER D. SWART, a citizen of the United States, residing at Auburn, in the county of Cayuga and State of New York, have invented certain new and useful Improvements in Corn-Husking Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.-

My present invention relates to corn-husking machines, and more particularly to the class in which the husks are moved from the ears by rollers, which being set at an inclination the ears are passed down this incline upon the rollers; and my said invention consists in certain new constructions and combinations of parts whereby new and desirable results are obtained.

In the accompanying drawings I have shown one way in which I have contemplated embodying my invention, and said invention is disclosed in the following description and claims.

In said drawings, Figure l is a partial side elevation of a corn-husking machine having my improvements. Figs. 2 and 3 are details of the construction of the band-cutter. Fig. 4 is a longitudinal vertical section, and Figs. 5 and 6 are details of parts.

In the drawings, A is the frame of the-machine.

B is the roller-frame carrying the huskingrollers, which in the main are of the "con struction and are connected and operated as shown in my former patents, Nos. 559,548 and 559,545, of May 5, 1896. It is usual in such constructions to employ some form of retarding device to prevent the ears of corn from passing too quickly over the rollers. In this instance I have shown a novel form of device for effecting this function.

In the brackets b b are journaled the rockshafts O 0. On these rock-shafts O C are mounted arms a 0. These arms have hubs loosely fitting the shafts and are secured thereto by pins orcotters o a, passing through slots 0 c in the said hubs. To each arm is pivoted a retarder-plat-e D of the form shown, the lower end being curved to permit the to remain at rest in their lower position. the shaft E revolves the pin e again rises 1n Serial No. 118,264. No model.)

' easier passage of materials beneath it. The

upper ends of these retarder-plates are bolted or otherwise secured to the hinge-piece d, and this piece d is pivoted to the arm 0 by the I pivot d., The construction is such that when the arms are raised the upper surface of the hinge-pieces d will after the arm has been slightly moved come in contact'with the under side of the arms a, and the retarderplates will then be raised with the arms. The general direction of the arms and retarderplates is toward the discharge ends of the husking-rollers and at an oblique angle thereto, so that they may be raised'by materials passing downward upon the rollers, as they are held to their lower position only by gravity. The plates are pivoted to the arms in the manner described, so that the retarderplates are free to rise independently of the arms when an ear of corn or other object comes against the lower end of the said plates with sufficient force. Loose ears or other materials of like character will be held by said plates from rapid movement downward along the rollers. These retarder-plates are stationary or occupy one position in respect to the husking-rollers; butin' order to prevent any stoppage of materials upon the rollers the retarder plates are momentarily raised to per- ..mit the escape of the materials held byrthem- Each of the shafts O is provided with an arm 0 outside of the brackets I). These arms are connected by a link e In or upon the frame A is mounted a shaft E, which is provided with a crank-disk 6, provided with a A pitman F is provided at its crank-pin e passes. The upper end of the pitman is pivotedto one of the arms 0 on the shafts C. The shafts are limited in their "movement to carry the retarder-plat'es down- 1 ward. When the shafts are in this position,

the crank-pin e moves downward in the slot in the pitman, permitting the retarder-plates As raising of the retarder-plates, which occurs intermittently during the operation of the machine.

The band-cutter of the machine is shown in Figs. 2, 3, and 4. The blades of the cutter are each composed of a circular disk having at two opposite sides projections, one edge of which is a helical curve and the other edge of which is a straight line approximating a radius of the said disk. The curved edges are sharpened for cutting the bands, as shown in the drawings. Each of these disks is provided at its center with an opening therethrough having eight right-angular portions, as indicated in Fig. 2.

In the drawings, G indicates the circular body of a cutter-blade, and g g the cutting projections, each of which has the sharpened helically-curved edge g and the straight edge 9 the edge g being sharpened to form'a cutting edge, as shown. The opening through the center of each knife is made with the eight angular portions 72. 7t 7L2 k h h h 71 The part of the shaft H upon which these blades are placed is square, and such shaft has reduced circular parts for its journals. These blades are placed upon the shaft with the short sleeves 2' between, the outer blades being secured with or without the intervention of sleeves. By reason of the particular configuration of the opening in each blade the same can be placed upon the shaft in eight differentpositions. Thehelically-curved cutting edge causes the knife to have a drawcut, which adds to its efficiency, while the form of opening in the blade enables the blades to be quickly put upon the shaft in the position desired.

\Vhat I claim, and desire to secure by Letters Patent, is

1. In acorn-husking machine, the combination with the bushing-rollers, of hinged retarder-plates extending toward the discharge ends of the said rollers and at an oblique angle thereto and means for giving said plates an intermittent rising-and-falling movement,

substantially as described.

2. In a corn-husking machine, the combination with the bushing-rollers, of a rock-shaft having connected retarder-plates extending toward the discharge end of the husking-rollers and at an oblique angle to said rollers and means for intermittently rocking said rockshaft to raise the said retarder-plates, substantially as described.

3. In a corn-husking machine, the combination with a rock-shaft, of arms mounted thereon with provision for slight movement independent of said shaft, and retarder-plates pivoted to said arms, substantially as described.

4. In a corn-husking machine, the combination with the rock-shaft and arms mounted thereon, of the retarder-plates pivoted to said arms to have a free movement in one direction only and means for intermittently rocking said shafts to raise said arms and retarderplates, substantially as described.

5. In acorn-husking machine, the combination with the husking-rollers, of the two rockshafts carrying the retarder-plates, of a crankdisk, and the pitman slotted to engage the crank-pin on said disk and connected with said pitman to produce an intermittent rocking of said rockshaft, substantially as described.

6. The band-cutter for corn'husking machines comprising the square shaft, the blades each having a cutting edge and having also an opening in said blade to. receive the square shaft, said openinghaving eight right-angular portions, and means for holding the blades in position, substantially as described.

In testimony whereof I aflix my signature in the presence of two witnesses.

LESTER D. SWART.
